淀粉衍生物的研究 Ⅰ高吸水剂性树脂的合成及其性能测定

Studies on starch Derivatives I The Preparation and Determination of Properties on Hight Absorbent Water Resin

本文利用资源丰富的天然淀粉,在催化反应条件下,与丙烯腈接技共聚,制的一种赋有新的性能的淀粉接技聚合物—高吸水性树脂。研究结果表明,该树脂可吸收自身重量100倍左右的蒸馏水,在PH=8左右,吸水能力最大,在电解质溶液、吸水能力有较大的改变。该树脂在压力条件下,可保持大量水份,这是其它吸水性材料所不具有的性能。从而使该树脂在卫生材料、医药、农业、园艺等领域,有着广泛的用途。

In this paper. we have prepared a new high absorbent water resin with natural starch and propenyl cyanide in catalytic action. Its properties have been determined under various conditions. The reselts show that the resin can absorb as much water as about 100 times the weight of its own. The resin has the largest absorbalility in ph = 8. The absorbalility has greater changes in electrolyte solution. The resin can maintain a large amount of water in the condition of pressure while other absorbent water materials can not. Ther afore,the resin can be widely used in medicine,agriculture and horticulture,etc.
